▎ 摘　　要

NOVELTY - Preparing filter paper-based flexible sensor comprises (1) uniformly mixing and stirring ascorbic acid (AA) and graphene oxide solution and adding to silver nanowires (AgNWS) aqueous solution to obtain mixed solution, (2) transferring mixed solution in polytetrafluoroethylene reactor and adding into oven, and reacting to obtain black mixed solution, centrifuging and washing to remove impurities to obtain Ag-rGO solution, (3) ultrasonically pulverizing Ag-rGO solution to obtain an Ag-rGO composite solution, dropping Ag-rGO composite solution on filter paper, and filtering and drying to obtain Ag-rGO filter paper, (4) adding filter paper into pressing groove of hot press, drying and cutting to shape, gluing copper wire to both ends of filter paper and drying in oven, applying layer of polydimethylsiloxane on surface, and drying, and (5) attaching double-sided tape to make adhere to surface of detection object. USE - The method is useful for preparing filter paper-based flexible sensor in technical field of flexible electronics. ADVANTAGE - The sensor has antibacterial function, high biocompatibility, micro-structure with great compressibility, stable high sensitivity, and inhibitsthe propagation and growth of bacteria. The method is simple, economical, high success rate, stable yield, high purity, and obtained material shape structure is controllable, convenient for mass production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation method of filter paper base flexible sensor with anti-bacterial function to claim.
